Move some service worker mojoms out of monolithic platform

The following service worker related mojom in blink will be used
from both //content and //components/services/storage when we move
ServiceWorkerStorage to the Storage Service:
* navigation_preload_state.mojm
* service_worker_database.mojom
* service_worker_registration_options.mojom

As described in crrev.com/c/1920008, putting these mojom in
the mojom_platform target causes some problems when we try to use them
from //components/services/storage. This CL gives them their own
mojom target the same way crrev.com/c/1920008 did.

These mojom files depend on web_feature.mojom and script_type.mojom.
web_feature.mojom has it own target. This CL also gives
script_type.mojom it own target.
